It is not the height of the second floor that creates the pressure, your
building probably has a negative pressure inside. I had a similar problem.
Connect a "runway" between window and hive (possible 20 cm long) and have
the runway open to the room , keep bees with wire mesh from escaping. The
cold air will rush into the room but not into the hive, water will not
condense at the hive entrance.
